Abstract
In this paper, exact solutions for free convection flow of a second-grade fluid with ramped wall temperature are obtained using the Laplace transform technique. The effects of pertinent flow parameters on velocity and skin friction are studied with the aid of various graphs. It is found that with an increasing second-grade parameter, the fluid velocity decreases for both ramped and isothermal wall temperatures and the skin friction increases. However, the magnitude of velocity in the case of the ramped temperature is quite smaller than the isothermal temperature for increasing values of the second-grade parameter.
